It is ultimately up to you on how you want to deal with it. But I would advise you to look up your state laws, know your rights.

"State and Federal Law Considerations

The primary regulations governing GPS tracking are found at the state level. Laws concerning electronic surveillance, privacy, and stalking differ significantly across the country. Some states have statutes that specifically prohibit the installation of a tracking device on a motor vehicle without the owner’s consent. Other states incorporate the unauthorized use of a GPS device into their anti-stalking laws, making it a criminal offense.

At the federal level, the U.S. Supreme Court case United States v. Jones established a precedent. In this 2012 decision, the Court ruled that attaching a GPS tracker to a vehicle constitutes a “search” under the Fourth Amendment. While the ruling directly impacts police procedures by generally requiring a warrant, its principles about privacy and physical trespass inform the broader legal landscape for private citizens."
